Step 1:: Identify the correct formula for the combined gas law
\boxed{\frac{P_{1} V_{1}}{T_{1}}=\frac{P_{2} V_{2}}{T_{2}}}
The correct formula for the combined gas law is given by option B:
Step 2:: Understand the variables
* 1$ are the initial and final temperatures, respectively.
Step 3:: Rearrange the formula for a specific goal
V_{2}=\frac{P_{1} V_{1} T_{2}}{P_{2} T_{1}}
If we want to find the final volume 1$:
Step 4:: Substitute the given values
V_{2}=\frac{(1.00 \text{ atm})(3.00 \text{ L})(350 \text{ K})}{(2.00 \text{ atm})(298 \text{ K})}
Assuming we are given the following values: * 1$ We can substitute these values into the formula:
Step 5:: Calculate the final volume
&= \frac{(1.00)(3.00)(350)}{(2.00)(298)} \text{ L} \
Now, we can calculate the final volume: \begin{align*} &= 2.06 \text{ L} \end{align*}
Final Answer
The final volume 1$ is approximately 2.06 liters.
